Penny Drop (Posted on 2013-01-17) Difficulty: 1 of 5
A toy wooden canoe is floating in a swimming pool.

Which will raise the level of the water in the pool higher:
Dropping a penny into the pool or, dropping the penny into the canoe?

The canoe already has a displacement.
It doesn't matter whether the penny is dropped into the water or the canoe, the water will rise according to the mass of the penny.

Consider it another way.
Dismiss the canoe completely.
Take two identical pennies and fashion one into a small canoe.
The displacement of the "penny" canoe will be the same as the one that was left intact.
